Every ocean lover knows the perils of having caught in the rip current. Experienced swimmers know it is actually comparatively very easy to escape the narrow channel of fast paced water by floating and letting it to drag you extra in the ocean or by swimming alongside the shore. However, novice beachgoers often panic, so you can swim to land, placing themselves liable to drowning as a consequence of fatigue. Based on the US National Ocean Service, the currents kill about 100 Americans annually and be the reason for 80% of lifeguard rescues. These scary statistics may soon often be a thing of the past, on account of Clever GIRL (Global Intelligent Rip Locator), a smart buoy that alerts swimmers with the existence of deadly rip currents.
The ingenious set up is the brainchild of Australian teenager Maddison King, who created Clever GIRL as the project for her Grade 12 Technology and design class. The 18-year-old, who functions as a lifeguard during her free time, developed the brilliant idea after finding that most youngsters were not able detect rip currents.
The basketball-sized plastic foam-filled buoy, that is placed on a series of similar devices or the ocean floor, is equipped which has a small propeller – akin to your one available on many boats. When the water starts to churn at speeds that has reached over 70 centimeters per second, it spins the propeller quick enough to power light atop the buoy, warning swimmers to remain seated away from the vicinity.
Though it appears with relative ease, their own children must overcome numerous design challenges so your float was effective, safe, and ecological. She picked a red light which is easy to see from the bright sunlight and as well as the color works as a universal wake-up call for tourists which do not speak any local language. The device’s smooth surface and handles ensure swimmers don’t get hurt, even though the black, white, and red striped underside, keeps sharks together with other animals from exploding. To prevent the turbine’s metal ball bearing from rusting, Maddison selected an environmentally-friendly waterproof marine grade lubricant. She also wishes to convey a siren to Clever GIRL’s next iteration.
Not surprisingly, the invention has earned Maddison numerous accolades, along with a finalist position along at the BHP Billiton Science and Engineering Awards, among Australia’s most prestigious student science awards. She also won a “Young Scientist Award” which qualified her to showcase the invention alongside 1,800 other students from 75 countries along at the 2017 Intel International Science and Engineering Fair.
Maddison, who may be currently seeking funding to create Clever GIRL to showcase, knows that the actual $300USD cost to help make the buoy is just too big steep to deploy the clever contraption across beaches worldwide. She, however, estimates the fact that cost can be reduced to some more affordable $100 USD the moment the system is manufactured in larger quantities. As for the name? The witty teenager believes it can be perfect seeing that “girls are cleverer than boys.”
